A team of astronomers using NASA's Hubble Space Telescope has taken an important step closer to finding the birth certificate of a star that's been around for a very long time. Estimates from observations dating back to 2000 placed the star's age at 16 billion years. This figure, if correct, would make it older than the universe's calculated age of about 13.8 billion years -- an obvious dilemma for cosmologists. The "Methuselah Star" has been known about for more than a century because of its fast proper motion across the sky. The high rate of speed is evidence that the star is simply a visitor to our stellar neighborhood. The latest measurements indicate that the star is 14.5 billion years (plus or minus 0.8 billion years), which still has astronomers scratching their heads. But at least that age is more in line with the estimated age of the universe.
